From Wikipedia
Greggs was founded by John Gregg as a Tyneside bakery in 1939. It opened its first shop in Gosforth, Newcastle upon Tyne in 1951.
When John died in 1964, the bakery was taken over by his son, Ian, assisted by Ian's brother, Colin. Major expansion began soon after, including the acquisitions of other bakeries such as Glasgow based Rutherglen in 1972, Leeds based Thurstons in 1974, Broomfields the Bakers, London, Bowketts the Bakers Kent, Tooks the Bakers (East Anglia) and Manchester based Price's in 1976.
In 1994, the company acquired the Bakers Oven chain of bakers' shops from Allied Bakeries.
